Possible Causes
Loose ribbon cable between display board and main PCB, Oxidized connectors from moisture, Faulty control panel PCB, Faulty main control PCB
How to Fix / Troubleshooting
Safety first: Unplug the multicooker before any disassembly.
- Power cycle: Unplug for 10–15 minutes, then plug back in. Sometimes transient communication errors clear after a full reset.
- Check for moisture: If steam has escaped around the control panel, allow the unit to dry for several hours in a warm, dry place before retrying.
- Button test: Verify that all buttons respond correctly. Unresponsive keys plus E8 often indicate a control panel fault.
- Internal inspection (advanced): Remove the top or front cover (depending on model) to access the ribbon cable between the user interface board and the main board. Reseat the connectors carefully.
- Repair: If reseating does not help, either the display/control PCB or the main PCB must be replaced. This should be done by a service technician.
